Twin bore lever type, is a 2 in and 2 out valve.
This valve enables the user to utilise original fluid pipe runs on Grp " N " or similar applications where a tandem master cylinder ( diagonal split system ) is specified.
This provides the driver, with seven distinct settings from which to select the most suitable braking ratio.
General description
These valves have been specially designed for use in competition vehicles where it is desired to reduce the hydraulic line pressure and therefore braking effort of the rear brakes to compensate for varying road/track conditions or vehicle handling characteristics.
Installation
To obtain the best performance using these valves, the brake balance should be biased towards the rear so that with the valve piped into the rear line and set in position 7 ( or the cap screwed right in ) where virtually no reduction occurs, the balance is as much to the rear as will ever be needed.
Placing the control lever in positions either 6 to 1 ( or screwing the cap outwards ) will progressively reduce the rear line pressure giving more bias to the front.
Warning
Due to internal adjustments set by AP Racing, do not strip these assemblies.
- DO NOT attempt any modification of these valves.
- Strictly for competition use only.
Note
These proportioning valves are suitable for use with any brake fluid that conforms to DOT3, DOT4 or DOT5.1 standards, but best all round performance will be achieved with either AP Racing PRF660 or 600 brake fluids.
